I don't know if it's just me or if there are others, but in recent weeks, OP messaged me inviting me to join or use their signature (Direct Invite). I had to decline it since I've been in the shuffle.com signature campaign since it started (more than 55 weeks) and I think that if I were to accept their offer, the signature campaign might not last long again. Anyway, I guess I wouldn't be surprised if jacksclub.io has signature campaign open again soon.
It is signal that they want to run another signature campaign but their method, like your reveal is not good. Sending PMs as invitations to join their signature campaign, can be reported and their account can be banned.Unofficial list of (official) Bitcointalk.org rules, guidelines, FAQ
29. Sending unsolicited PMs, including but not limited to advertising and flood, is not allowed.
They can open a thread and filter from applicants to pick best ones according to their team criteria of selection.
Maybe we have different approach to this. For me, if you ask me, I'm happy to receive this kind of PM or invitation for a signature campaign, knowing that they noticed & appreciate what I'm doing here on bitcointalk. The referral PMs are the ones I don't want to receive and those kinds of messages are more likely to be candidates for a ban, not the PM I received from the OP.
